The Corporate Information Transparency Index (CITI) annual green supply chain report was released on October 27, 2016 in Beijing. The report shows that many international and domestic brands are using public supervision data to expand green procurement in China and have pushed over 700 suppliers in China to improve their environmental performance.

In October 2016, IPE and Lvse Jiangnan continued their pollution investigation into Toyota Motor's supply chain in China, discovering that a number of automotive component suppliers belonging to Toyota Group have environmental violation records. Moreover, Toyota Motor's wheel hub supplier fails to properly store and treat its industrial solid waste and hazardous waste. In response to these violations, Toyota China breaks the silence with a response that it is currently checking these claims.

In September 2016, Lvse Jiangnan and the Institute of Public & Environmental Affairs conducted an investigative case study on Toyota's supply chain environmental pollution. The investigation shows that Toyota's subsidiary supplier has long exceeded air emission standards and has continually disturbed nearby residents. Despite its proposed goal to "reduce negative factors associated with automobiles as close to zero as possible," Toyota has yet to address its supplier's violations and keep to its environmental protection promise.

In August 2016, the Institute of Public & Environmental Affairs, Lvse Jiangnan and Huai River Guardians conducted a joint investigation, aiming to understand the supply chain management practices behind Disney's meticulously constructed green image. Investigations show that the brand has failed to meet its promises to "actively screen, evaluate and study the direct and indirect impacts its daily operations impose on the environment." Instead, Disney uses licensing as a way of shirking environmental responsibility.
